Floor Plan Suggestions For New Living Room?

Q: My husband and I just bought our first house and I'm not sure how to set the living room up. We would like for the room to hold our television, stereo system, space for playing music (we have an electric piano and smaller instruments) and to be comfortable for entertaining. We would also like to feature the fireplace without hanging the TV above it. There are also many doors and windows to work around. Any suggestions?
